GAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent N o. 685,446, dated October29, 1901. Application led October 26, 1900. Serial No. 34,523. (Nomodel.)

.T0 all whom it may oon/001%.'

Be it known that I, JAMES R. FLEMING, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inCarAxle Boxes, of which the following is a specification, referencebeing had therein to the accompany-4 ing drawings.

This invention relates to car-axle boxes and bearings; and the objectsof the invention are to simplify such boxes, to assist lubrication, andto make them more easily separable for the purpose of dismounting thecars used therewith, and other purposes, asset forth herein and are moreparticularly pointed out in the claims.

To these ends the invention consists of the construction,v combination,and arrangement of the several parts, as are herein described, andillustrated in the drawings, in which- Figure lis an outside elevation,looking toward the end of the axle, of the main castings constituting myimproved car-axle box. Fig. 2 is an under side view of the same, showingit in its relation to the carwheel and axle and showing by dotted linesthe method of sliding out the bearing from thev main casting. Fig. 3 isa side elevation of the same, taken at right angles to that of Fig. 1.Fig. 4 is a side view of the bearing when removed from the main casting.Fig. 5 isa view taken similar to that in Fig. 1 when the securing-key isremoved and cutting the sliding bearing on the line w a: of Fig. 3. Fig.6 is a diagramV showing a substitute pattern for the sliding bearing andits sliding ways. Fig. 7 is an additionalsubstitute pattern for thesame. Fig. 8 is another additional substitute pattern for the same. Fig.9 is a general view showing the parts of my device in the relationswhich they occupy when in use, the casting and sliding bearing being cutin crosssection on the line y y of Fig. 1.

Similar characters of reference denote like and corresponding partsthroughout the sevd eral views. n

Referring to the drawings, l designates the larger member of mydevice,being preferably a fiat cast-iron plate provided with holes 2 2,by which it may be secured to the body of the car. It is also providedwith an upwardlyis adapted to extend into an annular recess 8 j into thehubvof the car-Wheel l0, as shown in Fig. 9, the hub of the car-wheel l0having a part of its bore enlarged for that purpose. The' flanges 7terminate in a square shoulder 9, adapted to abut against the hub ofthewheel 10. The opposite or outer end of the journalbearing 6 is providedwith right and left extending wings or projections ll 1l, adapted alsoto prevent the bearing from sliding too far inwardly into the maincasting 1. The bore 12 in the bearing, which is adapted to receive thecar-axle spindle 13, is extended farther than the end of the spindle,thus forming a chamber 14, adapted to receive a lubricant or lubricantabsorbent, if desired. Lubricant is introduced into the chamber 14through the passage-way 15, which is communicated with through theoutside opening 16. (Shown in Fig. l.) When the sliding bearing 6 isinserted to its place, it is retained in position by means of a splitpin 17, passing through a lug 18, and the said pin is adapted to bespread by means of a wedge-shaped projection 19 on the outer end of thebearing member 6. This wedge-shaped projection is in line with the bore17' of the lug, and when the split pin is driven down through the saidbore-hole the wedgeshaped member spreads the end thereof, asparticularly shown in Fig. l, thus securing it from accidental removal.The pat tern of the downwardly-extending lugs and the engaging portionsof the sliding member 6 may be variously constructed in the substituteforms suggested in Figs. 6, 7, and 8, each of which is a diagram orpartial diagram of the cross-section of the sliding ways and lslidingbearing engaging with them.

My axle-box, as herein described, is more particularly applicable tosuch cars as are used about mines, where it may become necessary toremove the running-gears, or, in other words, dismount the cars bylifting them vertically off the axles, and my device is particularlyconstructed so as to furnish an improved lubricating arrangement by thesliding bearing extending into the hub of the wheel, as shown, and thewheel itself also revoluble on the spindle 13, and at the same time theconstruction permits the bearing 6 to be slid endwise o the axle-spindleand out of its sliding ways, as suggested in dotted lines in Fig. 2, andit is evident that when the pin 17 is removed and the weight of the carrelieved slightly from the bearings the bearing member 6 may easily beslid outward and o the spindle, after which the car-body may be lifteddirectly upward, releasing the axle entirely and facilitatingdismounting of the car.

I do not wish to be confined to the exact construction shown, as manyvariations in addition to those shown may be resorted t0 withoutmaterially departing from the spirit of my invention.

What I do claim, and desire to secure by Letters Patent, is

l. In a oar-axle box, the combination of two principal members, one ofwhich is a suitable bearing-plate adapted to be secured to the body ofthe car, and the said plate having downwardly extending flanges adaptedto grasp the other member which is a sliding bearing proper having acentral bore, and the said sliding bearing adapted to receive thecar-axle spindle within the said bore, and the said bearing furtherprovided with a cylindrical inner end annular in cross-section andadapted to extend within the enlarged bore of the car-wheel, incombination with a car-wheel having an enlarged bore forming with thespindle an annular recess adapted to receive the inner end aforesaid ofthe bearing, and the said parts separable by sliding endwise,substantially as specified.

2. In a car-axle box, the combination with a bearing-plate havingsliding Ways therein and a bearing proper adapted to slide horizontallyin the said bearing-plate, of a carwheel, having part of its boreenlarged and adapted to receive the inner end of said bearing propertogether with a car-spindle adapted to have the said wheel and bearingmounted thereon and removable therefrom, substantially as specified.

3. In a oar-axle box, the combination with the car-axle of two newmembers, separable bysliding longitudinally of the oar-axle, the one ofsaid members being adapted to be secured to the car-body, and providedwith a sliding way in which the other member is adapted to be slid, thesaid other member constituting the bearing proper, and being providedwith iianges on its outer end to prevent it from sliding too farinwardly, and a pin extending through a lug in the first member adaptedto secure said bearing from sliding outwardly, whereby the parts areheld firmly together when in operation, substantially as specified.

4. A car-axle box comprisin g two separable members, the one of saidmembers having an annular projection adapted to extend inwardly of thehub of a car-Wheel, the car wheel and car-axle adapted to be usedtherewith, the said car-wheel having part of its bore enlarged for thepurpose of accommodating the said annular projection, and the saidcar-axle adapted to iit the unenlarged bore of the car-wheel aforesaid,and to extend therethrough and into thecar-axle box, and the bearingmember of the said car-axle box being adapted to be slid outwardlongitudinally for the purpose of dismounting the'car from its axles,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES R. FLEMING.
